A cable management member is mounted between two slide rail apparatuses. The cable management member includes an arm assembly and a support member. The arm assembly includes a rear arm, a front arm, and a connecting member pivotably connected to the rear arm and the front arm. First ends of the rear arm and the front arm opposite to the connecting member are correspondingly pivotably connected to a stationary rail and a movable rail of one of the slide rail apparatuses. Opposite ends of the support member are correspondingly connected to the two slide rail apparatuses, and slidable relative to the stationary rails of the corresponding slide rail apparatuses. The connecting member is slidably supported on the support member. The connecting member includes a first positioning button and a second positioning button to restrict the support member therebetween, thereby preventing the support member from disengaging from the connecting member.
